To all whom it'may concern: Be it known that ELEAZER KnMrsnALL, a citizen of the United States, residing at Boston, in the county of Suifoil:

and State of Massachusetts, has invented certain new and useful Improvements in Methods of Making Tires, of which the following is a specification.

Tl'ie invention relates to an improved method of making vebicl'e'tires, havingparticular regard to the economic production of a tire of the resilient type, which shall be exceedingly durable and lasting in use.

In carrying out the process, the main features include the construct on or a tire made up of sections of materials-of varying degrees wear, and treating in effect an'integral whole. I

The sections forming the tire construction may be assembled in various ways to provide tires of relatively lifierent types, and the preferred sectional. constructions used in the present process are clearly shown in the'accompanying drawings, in which- Figure 1' isa broken perspective view of a tire showmg one form of arranging the respective sections. Fig.

2 is a longitudinal section of the same, prior to the final step of the process. Fig. 3 is a similar view of the coinpleted tire. Fig, 4 is a broken perspective, partly in longitudinal'section, showing a second form of sectionconstruction. Fig. 5 is a longitudinal section of a tire involving another form of section-arrangement. Fig 8 is a longitudinal section'of a tire, showing another form of section arrangement. Fig. 7 is a similar view Showing the tire illustrated in Fig. 6 after the final step in the process. Fig. 8 is a different form of tire formed by my improved process.

As basic statement of the present process I construct a tire of transversely-arranged sections of materials of different degrees of resiliency and durability, as rubber and leather, which sections throughout the length of the tire,- With their contacting laces initially secured together, as by cementing, or the like. The tire thus formed is submitted to a fusing process, such m vulcanizing, with the effect to fuse or secure the sections to praciicallyan integral whole.

In Figs. 1 to 3, inclusive, the'sectionsof material are of an outline corresponding to the shape desired for the completed tire, the rubber, .or similar sections of vulcanizable material 1, being ofsolidformation, while the leather, or similar sections 2, are each formed into a cenarranged transversely-disposed openiiig.3,"which of resiliency and resistance tothe tire so constructed in a manner,

non-resilient sections ofmaterial mation,

are disposed alternately rubber sections 1, giving the completed tire the construction shown in Fig.

In Fig. 4, the resilient sections 'of vulcaniaable mate rial 5, and relatively non-resilient sections 6, are of identical form, being each formed with a centralopening 7, and divided at their lower portions at S, forming the conventional type of tire. The outer surfaces or edges of the sections are inclosed in an envelop 9,, with a lining 10, also covering the edges of the sections within the opening 7.

portion, and said envelop and lining maybe of one intgral strip. In subjecting this form of tire to the final step of the process, the'cnvolop and lining will fuse with. the sections 5, forming an integral construction, as will be obvious.

In Fig. 5, the resilient sections of material 11,- and 12, are of identical construction with the exception that the resilient sections project slightly beyond the non-resilient sections at thetrcad portion of the tire. These projections 13, may extend any distance throughout the transverse circumferential dimension of the tire, though preferably limited to the tread portion thereof. The sections of material in this form are of solid for and terminate in alineinent at their inner edges to provide for an even bearing onthewheel-rim. In finally treating. the tire of this form, the sections are vulcanized as previously described, care being taken to avoid destroying the projections 13, for which purpose the vulcanizingchamber is preferably formed with notches 14, to receive the'depi'essions during the vulcanizing process. The form of the tire shown in Figs. 6 and 7, is somewhat similar to that shown in Fig. 5, except that in this instance theresilient sections of vulcanizable material 15, arelof greater area throughout than the non-resilient sections of material 16, so as to provide a portion .17, projecting from the resilient sections, beyond the non-resilient section. throughout the entire edge of tlie latter. In subjecting this form of tire to the final step the vulcaniziug chamber must .be of a size but slightly greater than the diameter of the nonresilient sections of material, so that the projecting portions l7, of the resilient sections of material Will be flattened and forced toward each other, andover the edges of the intermediate non-resilient sections of materiall Wlicn vulcanized projections ol'fthe adjacent resilient sections of material become in effect integral, thereby providing a strip integral with the resilient sections and overlying and inclosiug the non-resilient sections. 1

It is to be particularly noted that the final step of the present process forms an integral interbinding 0f the sections of material, so that the resilient sections The envelop may be, of any sectional. construction, though preferably thickest at the tread effective as the usual pneumatic type, without, of

course, being subjected to the disadvantages of the latter. The relativelynon-resilient sections of material increase the durability of the tire without interiering with its resiliency, owing primarily to the relative arrangement of the sections of material and their interconnection in the process.

In Fig. 8, the resilient and non-resilient sections are annular in formation, but the mode of treatment with my improved process is substantially the same as that heretofore described.
